ot ,quin or Celluloid of great density (5) is coatedon the seams or the hollowed place.

Thus treated, the pieces of leather which were sewed together have a very line exterior view, an optional pattern being had, and are most suited for manufacturing trunks or the like, duly guarded from agnail caused by fr'ctions, the seams are being pressed to hollow, and the agnail being` more etlectually prevented as a result of the said solution being` coated on the surface of the seams.

`Having thus described the nature of our invention, what we claim is l.
